Superman: Nightwing and Flamebird, Vol. 1 by Eddy Barrows, Julio Ferreira, Ruy Jose, Pere Pérez, Andrew Robinson, Renato Guedes, Diego Olmos, Greg Rucka

3.0

I enjoyed most of it, though there are parts which are a little uneven. Two more heroes go to Earth in Superman's absence on New Krypton. They're mistrusted by the population, hunted by the military and Kryptonians, and on a mission of their own.

The backstory given at the end was also helpful.
